Doesn't run

[dvdrbls]

Hi thank you for this package, used to run but not anymore, I don't know if are broken dependencies or else

[ollimacp]

When I run the main.go file, i get this.
go run cmd/physarum/main.go
cmd/physarum/main.go:8:2: cannot find package "github.com/fogleman/physarum/pkg/physarum" in any of:
/usr/lib/go-1.10/src/github.com/fogleman/physarum/pkg/physarum (from $GOROOT)
/home/username/go/src/github.com/fogleman/physarum/pkg/physarum (from $GOPATH)

also tryd to change "github.com/fogleman/physarum/pkg/physarum
into github.com/fogleman/physarum within the main.go file
cause the github repo is on this adress. Doesn't work either.

Just a few hints in the readme file would have been nice
Thx

This did the trick for me:
Init the module: go mod init github.com/fogleman/physarum
Install the stat module : go get github.com/gonum/stat

afterwards go run cmd/physarum/main.go should work.

I tried to make a branch/pull request to add a section to the readme but i don't have the permissions for that.

Thx :) go said it didnt know the mod command so after a quick search
i needed to update go cause i had 1.10 ---> https://stackoverflow.com/questions/60410729/unknown-subcommand-mod-error-while-running-go-mod-init

after then H4sh3's instructions worked!

Thanks that worked great for me!

I'm a bit confused on what you mean init the module?

as @H4sh3 Said

Steps -

1. Extract the package file to a location of your liking.
   Example c:\physarum-main

2. In cmd Navigate to the extracted folder
   Example Type "cd c:\physarum-main" in cmd window.

3. Run: 'go mod init github.com/fogleman/physarum'

4. Run: 'go get github.com/gonum/stat'

5. Run: 'go run cmd/physarum/main.go'

This will start the script. It however only generates png Images saved to the root folder c:\physarum-main.
If anyone knows how to launch a viewer so that you can watch the agents work please let me know!

Thanks to @H4sh3 and @aimsopp I got Physarum running, cheers guys : )

I carried on and got the viewer running too : )

Steps -

1. Installed mingw-w64 > https://sourceforge.net/projects/mingw-w64/files/latest/download
2. Added 'C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0' to system PATH variable
3. Opened CMD, navigated to 'c:\physarum-main'
4. Ran: 'go get github.com/go-gl/gl/v2.1/gl'
5. Ran: 'go get github.com/go-gl/glfw/v3.1/glfw'
6. Ran: 'go run cmd/viewer/main.go'

Basked in the glory of watching the agents do their thing!

Were you able to save sequenced .png files?

My apologies I'm a pretty big noob, could you go into more detail on how to do this I'm a bit confused.

No, I just got the viewer going.

I am new to Go, so I don't understand how it is supposed to work. But, I had a quick look and if you modify the file named 'Run.go' in the 'C:\physarum-main\pkg\physarum' directory, you can accomplish that.

The Run function starts like this:

func Run() {
if false {

Just change it to:

func Run() {
if true {

And it will do what you want.

@YukiCF How far have you got? Is it just getting it to run in viewer mode?

@YukiCF How far have you got? Is it just getting it to run in viewer mode?

I can see it run with the command Fogelman shared in twitter, or I can run it having individual pngs all different, but I want to save it sequenced to make a gif or a video of the physarum running

[AnderT]

Yes, if you edit the Run.go file as I have suggested that is what will happen.
